McHenry High School has PoolPak Dehumidifier Built on Site

How do you get a 24’x8’x6’ PoolPak SWHP190SR dehumidification unit through a 6’ wide door?

 

Hugh Flack was brought on as Facility Director at the school in 2017 and when he found that the existing PoolPak unit was due for replacement he contacted TEC. Jay DeStefano, Territory Manager and John Peloza, Product Manager met with the school and its Engineer, Wold Architects & Engineers, to help with the project. TEC was able to replicate the original unit with improvements such as variable frequency drives and premium efficiency fan motors. Wold also improved air distribution and quality with new duct work.

A problem arose when they were trying to figure out how they were going to get this huge piece of equipment through a 6′ wide door. The answer was piece by piece using PoolPak’s Build on Site program. PoolPak is unique with this offering. The unit was built at the factory and packed onto skids. A factory crew of four builders was sent to the job site to assemble the unit in four days. This crew was followed up by a factory startup technician and a TEC factory trained technician. The project timeline was tight, as most school summer projects tend to be. The general contractor, Irving Construction Company and the mechanical contractor C. Acitelli Heating & Piping Contractors worked together to get the pool back in operation on time.

TEC is the representative for PoolPak in Northern Illinois and Northwest Indiana. Please contact your Territory Manager for more information.

 

TEC & Magic Aire Exhibit at 2016 IASB Trade Show

On November 18th & 19th, TEC and Magic Aire hosted a booth at the Illinois Association of School Administrators & Illinois Association of School Boards 2016 Joint Annual Conference Exhibition. The booth exhibit featured the unique self-contained unit ventilator which incorporates packaged cooling and heating into a single unit, thus eliminating the added cost and maintenance for adding a remote condenser for cooling.

The unit has the highest part-load efficiency ratings in the industry due to a true variable speed compressor, as opposed to a 2-stage compressor like that of competitors. The sound is also a full 7 dB lower than older Magic Aire units. Models range from 2 to 5 tons and can include water, steam, electric heat or hot gas reheat. Models for 2017 include air and water source heat pumps.

School board members, facilities managers and engineers visited our booth and had the opportunity to appreciate this quiet and efficient unit.

Applications, Advantages & Highlights of KN Boilers

Modern boiler applications call for technology that is innovative, flexible and adaptable. KN Series cast iron boilers were purposefully engineered to live up to today’s toughest applications and challenges, providing versatility in boiler system configuration and installation without sacrificing the bottom line.

In this day and age, the word ‘hybrid’ gets thrown around often. But what about the terms ‘base load’ or ‘mixed-boiler? Within the commercial boiler market, the concept behind these configurations is simple, lower the upfront equipment cost of a complete condensing boiler plant by incorporating new units into an existing and less expensive non-condensing boiler plant.

With a hybrid boiler system that combines KN Series condensing boilers within an existing, non-condensing boiler plant, operators are able to meet total BTU requirements while optimizing overall system performance, increasing boiler efficiency under various climate, seasonal and load conditions. By operating during most of the heating season, the condensing KN Series units provide the bulk of the high-efficiency BTU output when loop temperatures are low, while the existing and less-efficient non-condensing units act as supplemental boilers when outdoor temperatures fall and boiler loop temperatures increase.

XeteX Custom Made Air Handlers – A Success Story

On an unusually cold day in May, Imperial Crane was lifting three XeteX custom made air handlers to the 11th and 7th floors of the new Midwest HQ of a multinational technology company, located in the west loop of Chicago. The lifts were accomplished with the 2nd largest crane in the Midwest, a 550 ton monster that lifted these 20,000 lb units to their final destination. But we’re getting ahead of ourselves.

In the Beginning

This story began in the spring of 2014 when the engineering firm of Environmental Systems Design called their Temperature Equipment Corporation (TEC) salespeople, Mark Simbrowsky and Jose Ronchetta to give them ideas about meeting a new building guideline called the Living Building Challenge© with an air handler that could handle the requirements of this demanding job. TEC knew immediately who to turn to for the job; XeteX, based in Minneapolis, MN.

Design Requirements

Part of the Living Building Challenge© requires:

  • Ventilation rates must be designed to comply with ASHRAE 62 and equipment must be installed to monitor levels of carbon dioxide (CO2), temperature and humidity.
  • Conduct air quality testing at pre-occupancy and after nine months of occupancy to measure levels of Respirable Suspended Particulates (RSP) and Total Volatile Organic Compounds (TVOC).
  • Provisions must be made for future enhanced filtration such as carbon filters, or more advanced products such as Secure Aire.
  • Monitoring is required to provide occupants opportunities for improving indoor air quality over time. Maximum thresholds will not be used to test compliance with the Living Building Challenge, but are listed in the Dialogue for reference. A minimum of one test is required for each separate HVAC system installed.

Therefore AHU’s were designed with the addition of innovative IAQ solutions to help qualify. One such product is Global Plasma Solution’s bi-polar ionizations I-Bars. These devices create positive and negative ions that are distributed across the cooling coil and propelled into the space to reduce or eliminate RSP’s and TVOC’s. Plus there is room in each AHU to install, at a later date Secure Aire filtration systems that use Particle Acceleration Control Technology and MERV 15 filters to reduce or eliminate RSP’s and agglomerate particles in the space to reduce TVOC’s and any other particulates that may accumulate in the environment. Also, room was left for a cooling coil and the units were built for the addition of compressors and condensing section once the building was occupied.

The purchase order was awarded during the Christmas holiday and the units were released for production in early March. Lead time was a tight 10 weeks, which is unheard of for a custom made unit. Also the delivery had to be timed exactly because of the crane involved. Any missed date of production, shipment or weather would have resulted in a large crane charge.

Given all that could have gone wrong, the coordination efforts of all parties combined to make this job a show piece for everybody.

 

Carrier’s Newest RTU Option – Dual Stage Relief Economizer

The patented and exclusive Dual Stage Relief Economizer is designed to provide all the functions of the typical air economizer while adding additional means to relieve building air pressure through the rooftop unit when required. All of this is achieved without adding an additional power exhaust system or a special central exhaust fan system and their related electric power source.

Dual Stage Relief Operation:

The 1st stage of natural relief is through the new dedicated air
chamber, and will provide relief when the building pressure
warrants regardless of the economizer damper positions or the
indoor fan status. A separate relief duct, must be installed in the return
opening in the curb.

The 2nd stage, which is the conventional natural relief of the
past, provides additional pressurization relief when the outside
air damper is mostly open and space pressure warrants.
